Answer:
13.76ft²
Step-by-step explanation:
Side of square: d=8ft
Area of board: Sb=d×d=64ft²
Area of circle: Sc=pi×r²=pi×(d/2)²=pi×d²/4=pi×64/4= 16×pi=50.24ft²
Remainin area: Sb-Sc=64-50.24=13.76ft²
Answer:
12 because u use the other shapes to reference your measurements.
100 and 110.
You would have to add 100 to both sides. This is because to complete the square, you need to take half of the x term and square it.
120-1/4x=80
-1/4x=-40
1/4x=40
x= 10
120-1/4(10)=80
80=80
